  • Here in VIC the law allows us 3% of leeway but I've seen signs on the freeway that says we are allowed a maximum of 7%. They must allow an additional 4% for margin of error in their radar guns

    • I think what VIC tells you is the "law" and what they do is different. All the news reports I've seen says that their fixed cameras give you a 2km/h leeway - not a 3%. Thus 113km/h in a 110km/h zone gets a ticket.

      • Last time I watched ACA they said they no longer advertise what the leeway is since their last revision of the law, and fair enough, but best guesses were that NSW was 2% and VIC was 3%. (or was it 2kph and 3kph - I've confused myself now)

        I've driven down EastLink at up to 110 (102) kph no problems (cruise control + downhill slope)

        • Yes, but whilst VICROADS and the RTA may not disclosure the leeway (that'll be changing in NSW if you believe Barry), when you start rounding up people who have been fined and look at their notices, that is when you can determine what the leeway is.

          Hence the 3km over = booking in VIC (at least the last time I looked). And whilst NSW might play hardball when they tell people what the situation is, the reality seems to be much different, with people not being booked until they're about 6% over on fixed cameras and 10% over on mobile.

          • according to "authorities" here in VIC, going 5km/h over the limit will automatically cause you to spear off the road and into a tree....

              Not to mention every km/h that you are over, a kitteh meets its end

              • Seriously?

                • Did the avg speed reset thing yesterday, which is kind-of annoying because it reset my avg fuel consumption & hours runs as well.....

                  100kmh on the speedo = 97kmh on the GPS = 95kmh on the digital readout. So if the digital readout is accurate (I believe the GPS is more accurate) then there was a >10% (12%-13%) difference between analogue & digital speeds when the car was fresh from the factory. No wonder everyone in the fast lane was zooming past.

                  • my speedo shows 140km/h, but the GPS says 130km/h...kinda feel ripped off, but VW tells me with its within tolerance.

                    I said to them will they refund me the 10,000kms worth of depreciation when my car hits 100,000km but has actually done abit over 90,000km....

                    they had no answer...

                      The speedo & odo are independant. I agree the odo still reads wrong but it isn't as bad as the speedo. You need to use one of those 5km long "Odometer check" strips that they have on motorways - the blue signs and use your tripmeter.

                      • brad, if your ODO is wrong, then that would be why your 'trip meter reset test' failed to get the same reading as a GPS.
                        Your ODO shouldn't be wrong unless there is some variation in your wheels/tyres from stock.

                        On my R, doing the 5km long check is perfectly accurate (within the errors of that check anyway), and the ODO matches the distance reported via a Tom Tom GPS, and the speed matches the trip meter average etc.

                        So in your case, adjusting the base value in VCDS to get the ODO back into an accurate position would be beneficial to you. It won't help the speedo being out.

                          • Just one question if possible. Is the MFD display of speed closer (not the average speed display) to accurate than the speedo?

                            • You tell us?
                              It completely depends on your car...

                              • Makes you wonder doesn't it? In my VW Jetta 1.6 TDI (as in most VW s I assume)
                                There are 3 speeds. One the digital readout; two the old needle on the dial and three the one you get if you put your watch together with the odo.
                                AND. They all disagree with each other AND they're all not correct.
                                Maybe doing mental calculations of 107% of speed limit signs is a cunning way VW has to keep my mind constantly working and alert , thus keeping my travel experience a safer one???????
                                Love my Volkswagen.
                                Love my GPS. Happy motoring.
